For Tata Steel’s India operations, the company has to use its captive iron ore which has an alumina content of 2.4 percent, whereas for its Europe facility, where the company is procuring ore from the market, it is choosing ore of a relatively lesser alumina content of 1.2 percent. Tata Steel Europe buys ore from a basket of suppliers such as Brazil, Russia, Canada, Norway, South Africa and Sweden.
High alumina in iron ore raises levels of alumina in blast furnace slag leading to adverse effects of the same on the latter.
“As our capacities increase, our requirement for ore will also go up and we can go up to 38 million tonne of iron ore via captive. So to that extent, the supply is ensured but as you see (citing the alumina example) everything has its own pros and cons,” Narendran added.
